Title: Binary circuit
IPC: H03K3/012
Filed: 1965-11-08
Abstract: 1,122,812. Bi-stable circuits. HEWLETTPACKARD CO. 8 Nov., 1965 [11 Jan., 1965], No. 47333/65. Heading H3T. A binary circuit comprises a pair of transistors cross-coupled through the emittercollector paths of a further pair of transistors (preferably of opposite conductivity type to the first pair), outputs being taken through inductive means from the inputs to the first pair of transistors. If transistor 9 is conducting, most of the current through resistor 23 flows through this transistor and little through transistor 19. Also, transistor 11 is non-conducting so that all the current through resistor 21 flows through transistors 17 and 31. The base of transistor 9 is thus held at a higher potential than the base of 11. A positive signal applied to the emitters of 9 and 11 cuts off 9 diverting current through transistor 19 and thus turning on 11. This now drains current away from transistor 17 and maintains 9 cut off. The inductors 37 and 39 speed up the changes in the base potentials of transistors 9 and 11. The common-base transistors 17 and 19 stabilize the collector potentials of 9 and 11 during the changeover, reducing the effect of basecollector capacitance. Similarly the commonbase transistors 29 and 31 stabilize the collector potentials of 17 and 19. Temperature compensation is provided by the symmetrical connection, of the base-emitter junctions of transistors 17, 19, 29 and 31 to the power supply.

Title: Apparatus for reading data from a memory element by using a magneto- or electro-optical effect
IPC: H04B10/06
Filed: 1969-09-26
Abstract: 1,241,916. Magneto-optical storage arrangements. INTERNATIONAL BUSINESS MACHINES CORP. 26 Sept., 1969 [2 Oct., 1968], No. 47509/69. Heading H3B. In an optical readout system, Fig. 2, which operates by detecting the amount of rotation experienced by a part M of a polarized light beam 29 when it passes through a data bearing magnetic memory element 30, noise from the light source 28, or from imperfections in the element, is removed by subtracting from the rotated part M of the beam a second part U whose wavelength(s) differ from that of part M in such a way that part U is modulated by noise but not by the data. After passing through element 30, beams M and U are separated by a dichroic mirror 31 and converted into electrical signals by photodetectors 32, 34. A capacitor 33 eliminates steady currents from the beam U, and the two signals are subtracted in differential amplifier 35 to give a relatively noise-free output 36. In the embodiment of Fig. 3, each beam is split into two polarization components by Woolaston prisms 42, 44, and then activates photodetectors 45, 46, 51, 52. The resulting four signals are subtracted in differential amplifiers 47, 54, to give signals Ua-Ub and Ma-Mb free of light source noise. After an adjustable delay to ensure correct phasing, further subtraction at 50 also removes memory element noise. In Fig. 6 (not shown), the two components from one prism are reflected on to the photodetectors of the second prism. In Fig. 5, beams Ub and Mb are derived by beam splitter 66 and dichroic mirror 70. These beams, which do not pass through the memory element, are subtracted from beams Ua, Ma at differential amplifiers 78, 79, to remove light source noise, and then further subtraction at 80 removes element defect noise. The waveforms of the signals and their differences are illustrated in Fig. 4 (not shown).

Abstract: 1464168 Sewing machines PFAFF INDUS TRIEMASCHINEN GmbH 5 Nov 1974 [10 Dec 1973] 47761/74 Heading D1G A sewing machine for sewing two superposed layers of material has an upper feeding foot and a lower feeding dog and means for automatically synchronising them so that they feed different materials at the same rate. The feed dog 8 is fed from two eccentrics 10 and 15; the feeding foot 7 is fed from an upper drive shaft 55 and a rocking shaft 63, itself driven by the upper drive shaft 55. The top feed is adjusted by rotating a disc 83 which alters the position of the various links and hence the stroke. Link 77 merely pivots about its lower end on the lever 78 and so does not alter the lower feed. Thelower and upper feeds may be simultaneously altered by rotating the disc 35. The two layers of material pass between three plates 103, 104, 105 and two measuring wheels 89, 90 monitor their speed. These wheels are connected to two Hall generators and when their speeds differ the Hall generators produce different rates of pulses causing a stepping motor 81 (Fig. 4) to alter the position of the disc 83 and hence the relative speed of the top and bottom layers of material.  The two layers of material are separated by a central plate 104 on a guide 102 (Fig. 2) which has raised spots 108 which nip the material to cause frictional drag: the material layers are caused in this way to move against a row of vertical pins 107 which act as edge guides.

In a track-laying vehicle, Fig. 1 (not shown), each end running wheel (3, 4) or (9, 10) for the two side tracks such as (2) is supported on one arm of a bell-crank lever (13, 24) or (32, 33), Fig. 2 (not shown), the other arm of which is coupled by a piston-rod, such as (14) for the lever (13), to an hydraulic piston-and-cylinder damping unit (15, 26) or (34, 35) each of which is connected by a conduit such as (16) or (17) to a pneumatic spring support unit (17, 28), or (36, 37). The conduits at each side of the vehicle such as (16, 17) are connected by conduits (18, 29) and (38, 39) to a common safety valve unit (19), (40), each of which is connected to, and mounted upon, an oil supply container (20). The conduits (18, 29) and (38, 39) are each connected, by way of a control valve (22, 31) or (43, 44), to a pump (23). The safety valve (19), which is the same as valve (40), comprises, as shown, a body having one-way valves 47, 45, which control the flow of fluid from the conduits 18, 29 to a valve chamber 46 which leads to an annular chamber around a spring-loaded valve 48 which is pressed against a valve seat 49 and which controls the flow of oil to the container 20. The valve member is urged upwardly by the fluid-pressure in the annular chamber acting upon a lower annular face 50 and downwardly to augment the spring 55, by the same fluid-pressure acting, through a duct 57 in the valve, a constriction 54, and a pressure space 53 upon an upper face 54. The space 53 is also connected to the oil container 20 by way of an auxiliary spring-loaded valve 58 and bores 59, 61 and a space 60 in the valve 48. One of the valves 45, 47, say the valve 47, as shown, opens at a predetermined high pressure of about 150 km./square cm. due, e.g. to a vehicle obstruction (62), Fig. 1 (not shown), the oil pressure build up acting upon the face 50 of the valve and propagating through the duct 51 and the constriction 52 and the space 53 to act equally upon the upper face 54 and the valve 58. The latter yields so that fluid flows from the space 53 to the container 20 through the hollow valve 48, the rapid decreases in pressure in the oil space 53 allowing the valve 48 to rise until the pressure in the space slowly equalizes through the constriction 52, and the valve member is returned to its closed position.
